Cancer occurs when cells in your body grow and divide out of control. Normal cells follow a regulated cycle of growth, division, and death. Cancer cells ignore these signals and continue multiplying, forming tumors or spreading through your bloodstream.
Different types of cancer affect different parts of your body. Colon cancer starts in the large intestine, while breast cancer begins in breast tissue. Each type has unique characteristics, but they share common features like uncontrolled cell growth and the potential to spread to other organs.
Some cancers develop due to genetic factors, while others result from lifestyle choices or environmental exposures. Early detection through screening and blood tests can help identify risk factors before cancer develops. Understanding your personal risk and taking preventive steps can make a real difference in your health outcomes.
